It looks like last call for alcohol at one Amagansett beach.

A partial booze ban is expected to take effect in August on weekends and holidays along a 2,000-foot stretch of Indian Wells Beach, East Hampton Town Supervisor Larry Cantwell said.

The ban -- requested by the beach's neighbors, who complained of rowdy behavior and public urination -- was approved unanimously on Thursday by the East Hampton Town Board.

The ban will be in effect when lifeguards are on duty, from 9 a.m. to 5 p.m., Cantwell said. The ban will take effect when the law is certified by the state secretary of state's office.

"We expect the law to take effect by Aug. 1," he said.

The town board initially weighed a proposal to ban drinking at Indian Wells and Atlantic Avenue beaches. That proposal was scrapped amid a dispute between the town board and town trustees over which body had jurisdiction over town beaches.

Town trustees, who generally are responsible for town waterways and beaches, instead accepted a modified proposal to ban alcohol only at Indian Wells.

Three people spoke about the law, mostly in favor of it, during a public hearing before the town board voted Thursday night.

Residents and officials said drinking at Indian Wells appears to have abated. Alcohol-related summonses are down this summer, after police had issued about 60 summonses in both 2012 and 2013 for violations such as public urination, littering and having open containers of alcohol, officials said.

"This summer has been more quiet than last summer," Cantwell said. "There has been some drinking this summer, but it's not as bad as last summer or even two summers ago."
